Welcome Ulireads

I reviewed your test sample, and while it sounds good there are some technical changes needed. LibriVox requires audio that is 128kbps constant bit rate MP3, 44.1kHz sample rate, mono, and between 86db and 92db, preferably 89-90. Your test audio settings are correct except for the volume, which is to low at 82.5db.

Make sure the the input gain slider in Audacity (upper right with the little mic icon) is well to the right. Then adjust the input gain on your mic so your raw recording has wave forms that peak at about the 0.5 marks in the Audacity window:

If necessary, adjust the volume level before exporting by going to Effects>Amplify.

You can pre-check your audio yourself by downloading the free Checker app: https://cgjennings.ca/projects/checker/
Passed with Warnings is a fail with regard to volume.
Go to Validation>Choose Validation Methods and check Background Noise. Be sure to leave 5 seconds blank at the end of your recording.
